The rebar straightening machine is mainly used to straighten various bent steel bars of different diameters so that they can be recycled and reused. The steel bar straightening machine has various models, mainly suitable for processing steel bars with a diameter of 6-25mm. The straightened rebars can be recycled in various construction and manufacturing industries.
This waste steel bar recycling machine is small in size and easy to move in different work scenarios. In addition, the machine is easy to operate and usually only one worker can operate it. It has a high processing efficiency and can process 30m to 35m of steel bars per minute.

Why recycle steel bars?
Recycling waste steel bars is not only economically beneficial, but also reduces resource waste and protects the environment. It is of great significance to the construction, manufacturing and recycling industries.
- Cost savings. Recycling and reusing scrap steel bars can significantly reduce the cost of raw materials in the construction and manufacturing industries, reduce dependence on new steel, and improve economic benefits.
- Resource recycling. Steel is a recyclable material. By recycling scrap steel bars, the demand for ore mining and smelting can be reduced, the service life of steel resources can be extended, and the development of a circular economy can be promoted.
- Reduce environmental pollution
Steel smelting is a high-energy, high-pollution industry. Recycling scrap steel bars can reduce greenhouse gas emissions, ecological damage caused by mining, and reduce the generation of industrial waste. - Improve construction efficiency. Many construction sites and demolition projects generate a large amount of scrap steel bars. If they are directly discarded, it will waste resources. However, after being reprocessed by straightening, shearing, etc., they can be reused in construction to improve the utilization rate of steel bars.
- Promote the development of the scrap steel market. The scrap steel recycling industry is an important part of the steel industry. The recycling and reuse of steel bars can support the development of the scrap steel market, create economic value, and meet the production needs of the steel industry.
